Application:
The RLA Series Style 2 Controller is a single circuit controller used to operate remotely located 12-vdc latching
solenoid(s) for domestic water services in a Residence.
This unit is provided with ISIMET latching circuit boards that permit a 24-vac signal to latch the solenoid(s)
ON and OFF, controlling the water supply to the residence. Freeze Protection is provided via a temperature monitoring
device that upon sensing freezing temperatures per a precise setting will operate the service solenoid to the closed
position, thus turning the water supply to the residence off. Optionally, a drain solenoid would open to partially drain the
service.
